Hi Keith, No hurry with the schematics. You are right about the fuses between the transformer and rectifier. By the way, I'm getting continuity through the fuses. My multimeter's 0.1 ohm resolution is plus or minus 0.8 percent plus 3 digits. I'm guessing this is too high? On the transformer, I was getting continuity between all the top terminals with just barely 0.1 ohm. Likewise, I get continuity on all the bottom terminals. I'm reading 10.8 ohms between the two outer terminals, 7.5 between the left and center, and 3.5 on the center and right. I'm not reading continuity between any of the terminals and the frame, or between the top and bottom sets of terminals. Does all this make sense? As for the diodes, I can't get a steady ohm reading on them in diode mode. Every once in a while the auto-ranger will blip but that's it. I'm getting continuity between all three rectifier leads. This means they're shot, right? So, when someone has time, would they be able to tell me what my readings mean? I'm sort of suspecting the transformer is bad. This thing only cost me a $1.50, so it's no great loss. Thanks.

Tractor Traction - by Chris Pratt. Our first bout with traction problems came when cultivatin with our Massey-Harris Pony. Up till then, this tractor had been running a corn grinder and pulling a trailer. It had new unfilled rear tires and no wheel weights. The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony. The seed bed was soft enough that the rear end would spin and slowly work its way to the downhill side of the gardens slight incline. From this, we learned our lesson sinc
